HL-200V /50 is a high poraler linear amplband all mode operation. It provides200W when driven by 50lnl radio.Using the built-in.l-ow noise GaAs FETtrL-ZOOV/50 enabl-es you to enjoy a more

ifier designed for l44l"l\za maximum output power of

receive pre-amp, thecomfortable VHF DX QS0.

IE4I!BE§L[D Power Level IndicatorYou can monitor the output povver level at all times. The outputpower is detected with the built-in precision microstrip linetype directional coupJ-er, and then fed to monolithic IC LEDdriver.

Protection Circuittlhen the connector at the RF output side is open or shorted, orwhen the suppJ-y voJ-tage gets over the ratinq, Frotection circuitswill operate to prevent the expensive RI power transistors frombe irrg danraged.

All Mode CompatibiJ"ity (SSB/r M/Clr)In Lhe SSB rnode, the time constant of the C0X (automatic sendreceive switch) is set to be approximatel-y one second.ConsequentJ"y, the reJ-ay rarel-y chatters during conversation,and smooth SSB operation is the result.Remote Send-Rec ieve Controlilrt)C or Sll0RTrrremote control lead wjres are incorporated.Connecting cabJ-es between remote send-receive conLrol terminalof the device and transceiver, a relay will not chatter atSSB/Clr,J mode, and a smooth transmission can be achieved.

l.Be careful of the following items which may become the causeof troubles.

The heat sink tempalatule will rise high during the transmission.Be carefuL not to block the heat sink surface to ensureventilation.

A1so, avoid operation near heat sources such as locationsexposerl to sunJ-ight or locations near heaters.

Be sure to check the I'Matching" or VS[n]R o1'antenna beforeoperation. Measure the SWR value by using an ShJR meteraccorcling to the installation on Paqe lt.II Sldtì value is too high, adjusl- yotrr artl.errna t-o obtaj.n a lowerSt/\JR value. You should obtain an StnlR of less than l.l: I orhopef uJ-1y as Ìow as 1.0:1.

will be dégraded within a few minutes alter starting trans-mission, due to the heating of the antenna. In some cases,the antenna may be damaged or destroyed'A1so, the RF pòwer transistors may be killed'

2.Please pay attention to the lollowing subject-s in order tokeep this amP in a good condition'

@ e:-e"s" use the coaxial cable as thick as possible '

O\Ae sure to use the 50Q coaxj.al cable. If you use the diflerentt-i*p.ààn.."«ir"n ui ZfA) cal; e, lt causes the mlsmatchlnq ofàn[ànnr, and you ""n not get the rated output power due toiÀ"i"rué of tÉe rellected polnler. It aLso becomes the cause

of the trounte-by-"*i=-'utching"' Choose the thicker cable toreduce the insertion loss of the output level '

Orn case of extending the power cable with other ones' be sureto use the thicker òaule than the allached one as short as
